[57] including the diffusion-controlled (DC) effects on bimolecular radical termination, propagation, and activation/deactivation reactions.
In Figure 6(b), outputs of unimolecular products IM1 and IM2 decrease with the increase of temperature, while output of bimolecular product [P.sub.1] shows the opposite.
The bimolecular recombination model [17,124, 134] was used, in a modified form initially by Koster et al.
The full ribo and the 2'O-methylribo modifications (Figure 9,1, 2) destabilized the monomolecular folds, like the GQs of the TBA, the htel-18 AGG[(TTAGG).sub.3], and the A(htel-21) GQs, and also bimolecular GQs in [Na.sup.+], such as the [[d[G.sub.4][T.sub.4][G.sub.4]].sub.2], whereas these two modifications stabilized the tetramolecular parallel GQ formed by T[G.sub.4]T oligonucleotides in both [Na.sup.+] and [K.sup.+] solutions [1].

Osterholtz and Pohl proposed a bimolecular nucleophilic displacement reaction consistent with their kinetic data, as depicted in Figure 9 for base catalysis of alkoxysilane hydrolysis, involving a pentacoordinate intermediate, and two different transition states, T.S.1 and T.S.2.
